What is the most common type of modification in a modern stand for?
Correct answer: B. Modulation / Demodulation
- A. Modification / DE modification
- B. Modulation / Demodulation
Explanation
In classical transmission system ,modulation and demodulation are the most common types of modifications made to a signal.Modulation: Modulation is the process of adding information to a carrier signal to create a composite signal that can be transmitted over a communication channel. The information signal, which can be voice, data, or video, is typically of a lower frequency than the carrier signal. By modulating the carrier signal with the information signal, the information can be transmitted over long distances.Demodulation: Demodulation is the process of recovering the original information signal from the composite signal received over a communication channel. This is done by removing the carrier signal from the composite signal, leaving behind the information signal.
